基于IEC 61850的变电站电能量采集终端的建模与实现

变电站电能量采集终端(ERTU)是用于变电站周期性数据采集的重要的厂站级设备,也是数字化变电站的组成部分之一.作为数字化变电站基础的IEC 61850标准并没有完全覆盖变电站电能量采集的全部测量量,因此,文中基于IEC 61850标准的扩展原则,扩充定义了一个公共数据类FEE、新的一组数据对象和一个逻辑节点MEEE,完整地建立了ERTU的对象模型,并进行了实例化.根据实际应用的需要,通过对ERTU和数字式电能表的分析,详细说明了建模过程并建立了符合IEC 61850标准的信息模型以及合适的服务模型.基于该设计的新型ERTU已在浙江某110 kV变电站投入运行.

Remote Terminal Unit Based on IEC 61850 for Energy Acquisition of Digital Substation

Electric energy remote terminal unit(ERTU),an important plant-level device for periodic data acquisition of substation,is obviously a part of digital substation system.However,as the basis of digital substation,IEC 61850 has not covered all measurement of quantities of substation electric energy.Therefore,based on IEC 61850 standard extend principle,a new common data class(CDC) FEE,a series new data object(DO),and a new logic node(LN) MEEE,are introduced to build a complete ERTU object model and its instanc...
